The AACLP has the potential to cause the loss of hundreds of acres of seepage wetlands as well as 34 acres of canal bank vegetation between Drops 2 and 3. IID has committed to expand/enhance the seepage wetlands complex between Drops 3 and 4 as compensation for the anticipated loss.

The habitat is characterized by several community types, including Freshwater Marsh, riparian woodlands, and scrub communities. Modifications to the physical characteristics of the canal (location and lining) may significantly impact groundwater elevations and water quality. Changing the groundwater characteristics may consequently affect existing and created/enhanced wetlands. Lining of the canal would reduce percolation of surface water. The resulting reduction in seepage and groundwater recharge and availability may impact the surrounding wetland habitat by reducing the water level and potentially eliminating wetlands at higher surface elevations. In addition, reduction in groundwater recharge with surface water from the canal may also influence water quality. Mitigation for potential loss of wetlands is one component of the AACLP and involves the creation and enhancement of 44 acres of wetland and riparian habitat within the approximately 2,000-acre wetland complex between Drops 3 and 4. This expanded/enhanced acreage will include 43 acres of honey mesquite and/or conttonwood willow, and one acre of marsh vegetation.
